sizzling :
If you want to eliminate screen tearing then you need to look at G)Sync or Freesync monitors. Problem with Freesync is AMD's latest generation of GPU's don't have anything to match a 1070 or 1080.
Also high fps especially in games like BF1 is very CPU dependent and is where an overclocked modern i7 excels. What system will you be pairing the gpu with?
I agree with what he said especially on
CPU dependency.
IDK about freesync, [strike]yuck AMD[/strike] I'm guessing it is the same concept as G-sync.
First of all Whatever you decide
DO NOT WASTE MONEY on a GTX 1080 please ... you will hate yourself later. if you need a 1080 wait a couple months for the 1080Ti.
also, some youtuber posted a video on BF1 frames stating: Ultra preset used with 1080p resolution.
FPS: Min 58/ Max 177/
Avg 107 with a Intel Xeon E3-1231 v3 CPU @ 3.6 Ghz turbo while gaming
an an MSI GTX 1070 Gaming X

Why G-Sync for tearing and 144hz gaming?:
Basically it syncs your Nvidia GPU frame output to the Monitor's refresh or hz. With a G-sync monitor you do not "need" a constant 144 frames to avoid tearing even if you drop below 30frames. As long as you are in the range of 100-144hz on a G-Sync 144hz monitor you wont even notice the frame dips. From 144 to 60 you might notice a small slowdown on your internal frame dip sensing radar, if you're a proper gamer that is
Anything above your refresh rate will have to be taken care of using V-sync or with RivaTuner's frame cap..
If you want I can test the game for myself using my i7 6700K and Asus Strix GTX 1070 stock and/or overclocked, just let me know.
Personal Experience gaming at a 100+ frames and 100+hz:
From my personal experience gaming at 120hz with 120fps for over 6 years the difference between 100fps-144fps is unnoticeable. I can in fact tell when my frames drop below 100 and I absolutely cannot play at 60fps on anything but casual games. My current screen is a G-sync XB240H 144hz 1ms. My old Alienware M17XR3 has a non G-sync 120hz (6ms
I think) screen and I never saw tearing from 100-120 frames.
SUPER simplified answer:
My answer to this would be get a GTX 1070 play below ultra for 144fps. Or play at ultra on a 1070 and get a G-Sync monitor then you wont even notice your frame fluctuations as long as you don't drop below 60. If you really want Ultra at 144 wait a few months for a GTX1080Ti DO NOT WASTE MONEY on a GTX 1080 please ... you will hate yourself later.
G-sync only works with Nvidia Graphics cards (minimum GTX650Ti) on DisplayPort
Extra Opinion on Monitors:
As for the monitor I highly recommend G-Sync it is awesome
I bought an Acer 24" XB240H 144hz 1ms Refurbished by Acer from Bestbuy for $299
http://www.bestbuy.com/site/acer-refurbished-xb240h-24-led-hd-gsync-monitor-black/5515004.p?skuId=5515004&lsft=ref:212,loc:1&ksid=3481855c-8570-4683-90e0-757660dd267b
It has a 3 year warranty included. Mine had no dead pixels no light bleed and was unscratched on the piano finished surfaces with the protective plastic still in place (the stand's base and the bezel are piano finish. The back is matte black the stand has a gun metal matte finish.)
Saved me $100
Setup needed a bit of tweaking.
Mine are
Brightness:100 (It is really really bright on 100 it competes with my 2 LED light-bulbs and when I first turned it up my eyes teared)
contrast: 60
Colour Temp:Normal
Gamma: Gaming (2.5 is fine too) You will also notice an OverDrive setting set it to Normal. Extreme causes reverse ghosting as well as overshooting the colors meanwhile off causes ghosting. OD basically over-volts the pixels to force faster response. If you want to see it in action use this while switching OD settings

Personally until now I have never found a screen that I preferred over my Alienware M17XR3's I think the glass panel on the alienware increased the overall clarity. Also the xb240H screen has nicer colors
(I did not need to change any colors in the Nvidia Control Panel)
If you have the money though, get the Acer Predator XB241H for $399
http://www.bestbuy.com/site/acer-predator-xb1-24-lcd-hd-gsync-monitor-black-with-red-accents/5159600.p?skuId=5159600 it includes a lot of fancy things features and is overclockable.
G-sync only uses DisplayPort the XB240H monitor only has a single DP available. The predator has an HDMI and a DP but only supports G-Sync through DP
